Designer Francis Sultana and architect Thomas Croft renovated a triplex apartment in a 19th-century London mansion for its art-collecting owner and her family. In the drawing room, a Steinway piano is positioned between a light sculpture by Elizabeth Garouste and Mattia Bonetti and a cabinet by Bonetti. Over the cabinet hangs a sculpture by Thomas Houseago, while a painting by Keith Coventry is displayed above a Martin Szekely console nearby. The clear cylindrical side table is also by Szekely, and the crocodile stool is by Claude Lalanne.

A sinuous mirrored table by Ron Arad separates twin sofas designed by Sultana; the white geometric side table is by Bonetti, and the carpet is by Fort Street Studio.

At one end of the drawing room, a Jean Royère sofa is grouped with Bonetti polished-steel side tables and a Charlotte Perriand bench with a cushion covered in an Edelman Leather cowhide; the large framed painting near the window is by Anselm Reyle, the photograph on the mantel is a piece by Marlo Pascual, and the pair of table lamps is by Garouste and Bonetti.
